Trump gained notoriety with his base for his plan to beef up security and build a wall along the border with Mexico. But it's his proposed deportation policy that could have the largest real-world impact on people currently living in the U.S.

As many as 11 million undocumented immigrants would be subject to deportation under Trump's campaign proposals. More than half of those — up to 6.5 million — would be considered "priorities" for removal. Trump has said he will build a "deportation force" with triple the existing resources to carry out his plan.

His vision on deportation presented a stark contrast to his Democratic contender, Hillary Clinton, who advocated for a path to citizenship for a broad swath of the undocumented population.

Those undocumented immigrants likely to face the immediate impact of Trump's victory expressed shock and dismay Wednesday morning. Already pro-immigrant advocacy groups said they were prepared for a political fight.

In disbelief that the KKK won. This is America. I won't stop organizing & will keep fighting for my parents & immigrants. #HereToStay
